Offered in a 1-7/8" diameter by 5/8" deep tin for use with shooting patches, this is the most amazing lubricant for long range black powder shooting. Invented by Steven Garby, one of the most consistent black powder metal silhouette match winners, ever. We've used everything in our Sharps and Rolling Block rifles, and nothing beats this stuff. Hand rubbed or melted and dipped on Maxi and Minie bullets, it will help prevent leading. Try it!
